Known for her acting roles in Just Go With It, What to Expect When You鈥檙e Expecting, and Grace and Frankie, Brooklyn Decker may be one of the busiest ladies in Hollywood. When she鈥檚 not killing it on set, running her wardrobe company Finery, modeling for Sports Illustrated, or partnering with cool brands, you鈥檒l find Decker chilling at home and spending as much time as possible with her precious boy Hank and husband Andy. Now, with the exciting news that baby number two is on the way, we recently got the chance to sit down with Decker and chat about her latest pregnancy, tips for moms-to-be, and current maternity style must-haves.

Brit + Co: Congratulations on expecting baby number two! How did your husband Andy react when he learned the exciting news?

Brooklyn Decker: We were both really excited. Terrified, but very excited.

B+C: You鈥檝e recently partnered with Clearblue to help launch a smartphone-enabled ovulation test 鈥 a product that you actually used to help plan for your new addition to the family. What made you choose this particular test to help with your personal family planning?

BD: A girlfriend of mine, who just had her third, recommended the Clearblue Advanced Digital Ovulation Test to me! I figured she would know better than most! I went back to work with my son when he was just weeks old 鈥 I wanted to plan this one a little better so I could give myself some more time and flexibility during that raw newborn phase. The new product has an app that you can use to track your personal cycle and know the best days to try.

B+C: Trying to get pregnant is often exhausting and frustrating. Do you have any advice for ladies who are trying to get pregnant?

BD: I just don鈥檛 think women realize how difficult it can be until we鈥檙e actually trying. We鈥檙e taught for years to NOT get pregnant, so most of us have no idea it can come with its challenges. My only advice would be to give yourself as much information as possible 鈥 which the new Clearblue Connected Ovulation Test System gave me 鈥 I didn鈥檛 know about cycle length, ovulation windows, et cetera before using Clearblue. I also encourage more women to talk about it so we don鈥檛 feel so isolated when things don鈥檛 go our way right when we want them to.

B+C: Are you someone who starts planning everything (buying baby clothes, designing the nursery, etc.) as soon as you find out you鈥檙e pregnant? Or are you more of a last-minute prepper?

BD: With my first pregnancy, I was into all the baby gear very early on 鈥 my label maker was my best friend. I did not recognize myself! With my second I have been SUPER lazy. That being said, I make sure all the clothes are washed and put away and the nursery is all set up. My goddaughter was born at 28 weeks, so I鈥檓 very aware that this whole parenting/pregnancy thing is out of our control. Again, control what you can, eliminate as much stress as possible, and surrender yourself to the rest.

B+C: Along with being an actress, you鈥檙e also the Chief Design Officer at Finery, a 鈥渨ardrobe operating system鈥 that makes it easy to catalog your apparel and plan outfits. How are using the system to help style your maternity looks?

BD: I use Finery as a productivity tool for my everyday life. I don鈥檛 want to be spending the 2.5 hours a week that most women spend picking out what to wear. I鈥檇 rather be hanging with my kid鈥 or sleeping! On Finery, I can plan all my outfits while I鈥檓 in a cab or waiting in line for coffee, and add them to my calendar so I get a reminder saying, 鈥淭omorrow it鈥檚 70 degrees and sunny, this is what you鈥檙e set to wear!鈥 I鈥檝e been traveling and working a lot with this pregnancy, so Finery has taken the headache out of planning, getting ready, and packing.

B+C: What are some of your maternity style essentials? Is there anything in your maternity wardrobe that you couldn鈥檛 live without?

BD: VERY stretchy leggings. And a few maternity shirts. My favorite maternity t-shirts are by HATCH, and my favorite leggings are by Spanx and David Lerner. They stretch with my expanding, swollen body, and I can throw on a boot and blazer and still look somewhat put together.

B+C: Going from one baby to two is a big transition. What advice have you gotten from friends and family about adding a new little one to the fam?

BD: I was in a business meeting recently, and the guy, who has three children, said to me, 鈥淓njoy the last few months of vacation!鈥 referring to me only having one child. I sort of gave off a terrified laugh; I loved his honesty. I don鈥檛 think I鈥檓 prepared at all 鈥 I鈥檒l get sleep when I can and hope for the best.

B+C: Finally, how did you introduce the idea of a new baby sister to little Hank? Do you have any helpful tips for preparing your kiddos for a new brother or sister?

BD: We started pointing out other babies when we would see them out and about, and we made a very big deal of him being a 鈥渂ig boy鈥 and a 鈥渂ig brother.鈥 We don鈥檛 even have the new baby here yet 鈥 so who knows if any of our tactics will work. He may transition terribly! I鈥檒l keep you posted鈥
